Specification forming part of Letters. Patent No. 69,047, datedSeptember 17p, 1567.

To` all whom it may concern:

Be it known that we, T. G. THOMPSON, of the city of Richmond, in thecounty of Wayne and State of Indiana-and A. F. FOX, of the town ofGreensborough, in the county of Henry andState of Indiana, have inventeda `new and useful Improvement in Selil Acting `Hand- Looms, ofwhich thefollowingis a full, clear, i

a carrier which is caused to bear upon the inclined surfaces, saidcarrier being secured to the trip which depresses the treadles and givesmotion to the harness; also of a hinged handle secured to the center ofthe front surface of the batten, by means of which the machine is put inmotion; and also of a continuous spring secured to the under side of thebatten and connecting with the triggers.

Figure l is a perspective view of our improved self -acting hand-loom.Fig. 2 is a transverse section ofthe batten and elevation ofthelatch-bar Aand cam which give motion to the iinger-bar for depressingthe treadles.

Fig. 3 is a plan of the batten and warp-protector attached thereto, andthe latch-bar, cam, carrier, linger-bar, and treadles. Fig. 4 is aperspective view of the latch-bar, cam, and carrier. Fig. 5 is anelevation of the guide to the ratchet-bar, the ratchet-wheel, and pawlwhich give motion to the cloth-roller. Fig. 6 is a plan of the underside of the batten, show- Aing the continuous spring, the trigger, and

pickenbar.

A is the frame of the loom. B is the batten,

` to move `freely between the guideandfpost.`

This bar carries the pawl 61engagingfthe j ratchet-wheel e, secured to`the cloth-roller I The front wall of"` each shuttlefbox g is slot-..1`ted, and haspivoted init the retainingblock h. l

A rod, is held insuitable bearings in front v ofthe batten, and extendsfrom one `shnttle- 1 l1 box g tothe other. `The `ends of lthe lrod .arelprovided with conipressingrleversk. Theyare i causedto bear upon theretaining-blocks .hI by-` p the springs l. i n j At or near thecenteroftherod i is secured the detaining-arm on, projecting `towardthey front, which `arm impinges` upon thetblockm j attached to thebeam n',whenthe shuttle is j i v not properly boxed.

Beneath the block oiisthe recess a in i beam n', into which thedetaining-arin enters i when the shuttle is properly boxed. i

o and the beam n.

The front end, p, of the latch-bar C `is turned inward at right angles,andA the pin gis se cured to and projects inward from the latch-l bar G,at sucha distance from the end pof p the bar as will permit thenecessary motion back and forth of the post a of the batten.

A hook, i", upon the under side of the latch-1` bar, near its inner end,engages the pins s', projecting fromthe ratchet-cam s, which isjournaled on a stud attached to the frame A.` f i A carrier, D, bearsupon the ratchet-surfaces of the cam s. It is attached in a securemanner at one end to the finger-bar E The nger-bar E is pivoted in therotating post t, i i

pendent from the beam n'.

A spring, t', made fast `to the post t and l.

beam a, by its elasticity causes the finger-bar E to constantly pressthe carrier D upon the face of the ratchet-cam s. The liberated end ofthe nger-bar E presses down alternately l the ends of the treadles F,whereby motion is given to the harness Gr.

To the center of the batten ,and on its front tion to the loom.

An adjustable hanger, I, is secured to the longitudinal rail of theframe A, and is slotted for the purpose of giving a lateral motion tothe carrier D. The screw u, which secures it to the frame, is readilyremoved to permit the adjustment.

Upon the under side of the batten B is secured the springl, which hasits outer ends connected with the triggers C, for the purpose ofreturning the triggers, after theyhave been disengaged from thepicker-sticks, to a position to again hold the sticks when they arepressed back.

The operator applies both hands to the handle H of the loom, draws thebatten forward, when, in case the shuttle landsin either shuttle-box g,the detaining-arm m passes beneath the block n, entering the recess n,which permits the full forward motion of the working parts of themachine; the post a, of the batten having in the meantime engaged the lfront end, p, of the latch-bar C, which, in its the pin g in thelatch-bar O, moving it back until the hook r engages the next pin s ofthe cam s. Now, should the shuttle, which, when properly thrown, isretained in place in the shuttleebox g until the picker-block strikesit, from any cause whatsoever, be detained in its motion from oneshuttle-box g to the other, the retaining-block h is not pressed out,and the detaining-arm m strikes the block n attached to the beam n',instantly notifying the operator that the process of weaving cannot beproceeded with until the necessary repairs shall have been made or thecause of derangement removed.

What we claim as new, and desire to secure by Letters Patent, is-

1. The sliding latch-bar C, having projections q and p, in combinationwithV the posts a of the batten B and the ratchet-cam s, arranged andoperating in the manner set forth.

2. The combination and arrangement of the spring Z, constructed asdescribed, with the lay-triggers and their operating-straps, as and forthe purpose described.

3. The handle H, combined with the battentop, in the manner described,and for the purpose specified.
